DA9210 Multi-Phase 12 A DC-DC Buck Converter

General Description

DA9210 is a multi-phase synchronous step-down converter suitable for supplying the CPU power in

automotive in-vehicle infotainment systems, smartphones, mobile computing, and other handheld

applications, which require high currents to run the processor core.

DA9210 is designed to operate with four phases, each phase using a small external 0.47 µH

inductor. The buck is capable of delivering up to 12 A continuous output current with an output

voltage of 0.3 V to 1.57 V. The input voltage range of 2.8 V to 5.5 V makes it suited for a wide variety

of low voltage systems, including all Li-Ion battery supplied applications. Two DA9210s can be used

in parallel to deliver an output current of up to 24 A.

The DA9210 point-of-load remote-sensing feature guarantees the highest accuracy while supporting

multiple PCB routing scenarios without loss of performance. The highly-integrated design removes

the need for external switching FETs or Schottky diodes.

A programmable soft start-up can be enabled, which limits the inrush current from the input node and

ensures a slope controlled activation of the rail.

The Dynamic Voltage Control (DVC) supports adaptive adjustment of the supply voltage dependent

on the processor load. This is done via direct register write through the communication interface (I²C

or SPI compatible), via the dedicated DVC control interface, or via a programmable input pin.

DA9210 integrates over-temperature and over-current protection for increased system reliability,

without the need for external sensing components. A Power Good and Over-Current Alarm output

informs the CPU of an out range voltage output and if the current exceeds a programmable limit,

thereby enabling the processor to reduce its consumption before the supply rail collapses.
